<ul><li>1、This demonstrator can vividly demonstrate the principle of submarine ups and downs, and understand the laws more vividly and intuitively. 2、The demonstrator of the principle of submarine ups and downs can help students deeply understand the practical application of Archimedes' law. 3、Small and portable physics teaching instrument, simple and easy to operate, convenient for students to do it themselves. 4、When doing this experiment, you need to bring your own transparent water cup or beaker, and pour 3/4 of the water into it. 5、Do not collide or drop the diving ball gas chamber and the transparent water tank, so as to avoid rupture, prevent contact with gas, to prevent aging and cracking.
Item Type: Submarine Demonstrator Material: ABS Experimental Principle: Experiment according to Archimedes' law How to Use: 1. Bring your own transparent water tank or beaker (diameter greater than 10CM, height about 15CM), and pour 3/4 volume of clean water into the transparent water tank. 2. Push and pull the piston several times in the suction and exhaust cylinder in the water to make the piston and cylinder wall lubricate and seal, and push the piston to 10 ml near the top. 3. Weigh the submarine's own weight with a bar box dynamometer and make a record. 4. Connect the suction and exhaust tube with the suction and exhaust holes of the submarine's air chamber with a transparent plastic tube, and then gently put the submarine into the water. At this time, the submarine floats on the water. 5. Slowly pull the suction and exhaust cylinder outwards, the submarine's air chamber is exhausted, and water is sucked in from the bottom water inlet. At this time, the submarine sinks slowly as its weight increases. 6. Weigh the submarine with a dynamometer and record the weight of the sphere. 7. Push the piston in again, the air chamber inhales, the drain hole drains, the weight of the submarine gradually decreases and floats slowly, and then the weight of the diving ball is weighed with a dynamometer, which is just the weight of the ball itself.
